Description

Technical Field

[0001] The utility model relates to the technical field of intercepting pipe manufacturing, in particular to a modular quick-detachable intercepting pipe. Background Art

[0002] Interceptors are widely used in liquid delivery pipelines. In some material delivery processes, interceptor tubes are used as switch valves; that is, when the pump body draws the material out of the tank, the interceptor tube is in a closed state, and when the material is pumped out, the interceptor tube is opened and the material is injected into the container from the interceptor tube.

[0003] When conveying materials with high viscosity, the materials often adhere to the intercepting pipe, causing the intercepting pipe to be unable to be used normally. Therefore, the intercepting pipe needs to be maintained regularly. Since the materials on the surface of the parts are difficult to be thoroughly cleaned, the method of directly replacing the parts is often used for maintenance. However, there are many non-standard parts in the existing intercepting pipe, which not only leads to an increase in the production cost of the existing intercepting pipe, but also requires additional configuration of corresponding parts for replacement, which increases the use and maintenance costs. Therefore, the existing intercepting pipe structure needs to be further improved. Utility Model Content

[0028] The utility model is further described in detail below with reference to the accompanying drawings:

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0032] like Figures 1 to 6As shown, a modular quick-release shut-off pipe comprises a shell module, wherein the shell module comprises a first shell 1 and a second shell 2 connected to each other, wherein the first shell 1 is provided with a liquid inlet 1a, and the second shell 2 is provided with a liquid outlet 2a, wherein the first shell 1 is connected with an intermediate frame 3, and a standard cylinder module 4 is installed on the intermediate frame 3, wherein a piston 41 is provided in the standard cylinder module 4, and one end of the piston 41 extends into the intermediate frame 3 and is connected to a quick-connect plug 6 through a quick-release joint 5, wherein the quick-connect plug 6 is connected to a shut-off rod 7, and wherein the shut-off rod 7 is provided in an inner cavity which passes through the first shell 1 and the second shell 2.

[0033] The piston 41 is connected to the quick-release connector 5 via a quick-connect nut 51 .

[0034] Since the quick-connect plug 6 and the shutoff rod 7 are relatively long, the shell module of the shutoff pipe of the present invention adopts a two-section structure consisting of a first shell 1 and a second shell 2, which greatly facilitates the connection of internal components.

[0035] The standard cylinder module 4 is a standard cylinder that can be purchased on the market, and the parts are easy to purchase and the manufacturing cost is low.

[0036] A first flange 81 is disposed at the front end of the intermediate frame 3 , a second flange 82 is disposed at the rear end of the first housing 1 , and a first gasket 83 is disposed between the first flange 81 and the second flange 82 .

[0037] The first flange 81 and the second flange 82 are connected and fixed by a first clamp 84 , and the first clamp 84 is provided with a first limiting groove 84 a with a trapezoidal cross-section.

[0038] The connection between the intermediate frame 3 and the first shell 1 is achieved through the cooperation of the first clamp 84 with the first flange 81 and the second flange 82. A first gasket 83 is arranged between the first flange 81 and the second flange 82 to ensure sealing. After the first flange 81 and the second flange 82 are matched, the first clamp 84 is wrapped around the outside. Since the first clamp 84 is provided with a first limiting groove 84a with a trapezoidal cross-section, when wrapping, the first flange 81 and the second flange 82 can be retracted inward by utilizing the inclined surface of the first limiting groove 84a, thereby improving the reliability of the connection.

[0039] A third flange 85 is disposed at the front end of the first housing 1 , a fourth flange 86 is disposed at the rear end of the second housing 2 , and a second gasket 87 is disposed between the third flange 85 and the fourth flange 86 .

[0040] The third flange 85 and the fourth flange 86 are connected and fixed by a second clamp 88 , and the second clamp 88 is provided with a second limiting groove 88 a with a trapezoidal cross section.

[0041] Similarly, the connection between the first shell 1 and the second shell 2 is achieved through the cooperation of the second clamp 88 with the third flange 85 and the fourth flange 86. A second gasket 87 is arranged between the third flange 85 and the fourth flange 86 to ensure sealing. After the third flange 85 and the fourth flange 86 are matched, the second clamp 88 is wrapped around the outside. Since the second clamp 88 is provided with a second limiting groove 88a with a trapezoidal cross-section, when wrapping, the third flange 85 and the fourth flange 86 can be retracted inward by utilizing the inclined surface of the second limiting groove 88a, thereby improving the reliability of the connection.

[0042] The intermediate frame 3 is provided with a through slot 3a, which facilitates the assembly and disassembly of the quick-connect nut 51 and the quick-disconnect connector 5.

[0043] The standard cylinder module 4 is provided with an air inlet 4a, and the air inlet 4a is provided with an air source quick connector 42. The provision of the air source quick connector 42 facilitates the connection of the ventilation pipe.

[0044] The liquid inlet 1a is provided with a ferrule 11. The provision of the ferrule 11 facilitates the connection between the pipeline and the liquid inlet 1a.

[0045] Working principle:

[0046] When the intercepting pipe is working, the vent pipe is connected to the standard cylinder module 4 through the air source quick connector 42, and the reciprocating motion of the piston 41 in the standard cylinder module 4 is realized through the air intake control. The piston 41 is connected to the intercepting rod 7 through the quick-connect nut 51, the quick-disconnect connector 5, and the quick-connect plug 6. The intercepting rod 7 is driven to reciprocate by the piston 41, thereby realizing the closing or opening of the end of the intercepting rod 7 and the liquid outlet 2a of the second shell 2. Here, the end of the intercepting rod 7 is provided with a cone surface with a cone angle (the angle between the cone surface and the horizontal plane) of 65°, and the inner wall of the liquid outlet 2a is provided with a cone surface with a cone angle (the angle between the cone surface and the horizontal plane) of 60°. In this way, the intercepting rod 7 forms a line contact with the liquid outlet 2a when it is closed, which can better play a sealing effect.

[0047] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
